Frequently Asked Questions - ROG Strix XG34WCDM ASUS

How do I clean the ROG Strix XG34WCDM monitor?
Turn off the monitor and unplug the power cord. Use a lint-free, non-abrasive cloth. For stubborn stains, dampen the cloth with a mild cleaner. Never spray cleaner directly on the screen, and avoid alcohol or acetone as they can damage the display.
What is the maximum refresh rate and how can I enable it?
The monitor supports up to 240Hz refresh rate. To enable it, connect via HDMI 2.1, DisplayPort 1.4, or USB-C and set the refresh rate to 240Hz in your device's display settings. The monitor also supports Variable Refresh Rate (VRR) from 48Hz to 240Hz to eliminate stuttering and tearing.
Does this monitor support HDR content?
Yes, it supports multiple HDR modes such as Gaming HDR, Cinema HDR, Console HDR, DisplayHDR 400 True Black, and Dolby Vision (Bright, Dark, Gaming). Some picture settings are disabled when HDR is enabled.
Can I mount the monitor on a wall?
Yes, the monitor is compatible with a VESA 100 x 100 mm wall mount. Press the release button to detach the stand, then install the VESA wall mount kit. Use a UL Listed bracket that can support at least 12 kg.
What is Pixel Cleaning and when should I use it?
Pixel Cleaning is an OLED maintenance function that calibrates screen issues after long use. It takes about 6 minutes and automatically activates when the monitor is turned off. Do not unplug the power cord during the process. For best results, run it after the initial use or after the screen stays on for extended periods.
What smart features does the ROG Strix XG34WCDM include?
The monitor runs Google TV, featuring built-in WiFi 6E, Bluetooth 5.3, a remote control with voice search and streaming shortcuts, Miracast wireless screen mirroring, MultiView split-screen, CrossShare file sharing, and access to the Google Play store.
How do I use MultiView to display two sources at once?
Open the Shortcut Menu, select the Multi-View icon, then assign one source to Main (via HDMI/DP/USB-C) and another to Sub (including Miracast). Choose a layout and confirm. The Sub source does not support HDR, and Main and Sub cannot use the same port simultaneously.
How can I adjust the OSD settings?
Press the ROG button on the remote control or the 5-way button on the monitor to open the OSD menu. Navigate using the arrow keys, confirm with the OK key, and use the Shortcut Menu for quick adjustments like volume, input source, and display settings.
What safety precautions should I follow when installing the monitor?
To prevent tipping, securely attach the monitor to a wall using a cord or chain that can support its weight, especially if a wall mount is used. Always place the monitor on a stable, level surface, route cables to avoid tripping, and never block the ventilation slots. Use a UL Listed power source and avoid exposing the monitor to rain or moisture.
What are the recommended cleaning and care steps to avoid screen damage?
Disconnect the power cord before cleaning. Wipe the screen with a dry, lint-free cloth. For stubborn dirt, use a cloth slightly dampened with a mild cleaner designed for LCD/OLED screens. Never spray liquid directly on the screen, and never use alcohol, acetone, or abrasive materials.

Web Content Accessibility Guidelines (WCAG) from the W3C's Web Accessibility Initiative (WAI) helps web designers and developers create sites that better meet the needs of people with disabilities or age-related limitations. WCAG advances accessibility across the full range of web content (text, images, audio, and video) and web applications. WCAG can be precisely tested, is easy to understand and use, and allows web developers flexibility for innovation. WCAG 2.0 has also been approved as

ISO/IEC 40500:2012. https://www.asus.com/content/accessibility-policy/

WCAG specifically addresses barriers to accessing the web experienced by people with visual, auditory, physical, cognitive, and neurological disabilities, and by older web users with accessibility needs. WCAG 2.0 provides characteristics of accessible content:

- Perceivable (for instance, by addressing text alternatives for images, captions for audio, adaptability of presentation, and color contrast)

- Operable (by addressing keyboard access, color contrast, timing of input, seizure avoidance, and navigability)

- Understandable (by addressing readability, predictability, and input assistance)

- Robust (for instance, by addressing compatibility with assistive technologies)

b. Recommended image size:

Image Data typeMaximum resolution recommendationAttention
JPEGBaseline 16384 pixels (x16384)
Progressive 3840x2160
PNG 4096x4096 The maximum resolution depends on the size of DRAM

2.3.3 Image Scaling Rules

a. The image is scaled proportionally based on the screen height (smaller images are enlarged, larger ones are reduced).
b. The left portion of the image fills the left black area of the screen.
c. The right portion of the image fills the right black area of the screen.

Special Cases:

If an image is too tall and too narrow, scaling it proportionally to fit the screen height may cause insufficient width to cover the letterbox areas.

In this case, the image will be stretched horizontally (non-proportional scaling) to fill the black side areas.

Since this feature is designed specifically to fill the left and right sides of the screen, it is recommended to use images with an aspect ratio close to 21:9 (e.g., 3440×1440) for the best visual result.
